Notes
※1. Internal input resistance of volt-ohm meter should be higher than 10k-ohms.
テ ス タ ー は 、 入 力 抵 抗10kΩ 以 上 のもの をお使 い下さ い。
※2. Adjustments should be made in case of the PC Board or Transistors being changed.
調 整 はPCボ ー ド あ る い は ト ラ ン ジスタ を交 換した 場合に 行って 下さい 。
※3. After feeding 1～10 watts output for about 15 minutes, check bias adjustment again.
